SAFETY-RAZOR.

Specification of Letters Patent.

Patented Jan. 191-1.

Application filed November 16, 1909. Serial No. 528,321.

To all whom it may concern:

Be it known that I, LUIGI BnUNAcoI, a

subject of the King of Italy, and a resident of New York, county andState of New York, have invented certain new and useful Improvements inSafety-Razors, of which the following is a full, clear, and exactdescription.

This invention relates more particularly to means for locking andclamping the blades of safety razors.

The primary object of the invention is to provide simple and efficientmeans whereby the backing member may be quickly and effectively lockedto the guard member in such a. way that afiexible blade with one or morecutting edges may be clamped and held between the said members in such away that the blade will cut properly while shaving without the liabilityof injuring or cutting the skin while in use.

A further object of the invention is to provide simple andeflicientmeans whereby the backing member may be entirely removed fromthe guard member to adapt a blade to be inserted or removed at will, andthe said device so constructed that by a rotary movement of the lockingmember, the said backing member will effectively and rigidly hold theblade against the guard member.

With these and other objects in view, the invention will be hereinaftermore particularly described with reference to the accompanying drawings,which form a part of this specification, and will then be pointed out inthe claims at the end of the description.

In the drawings, Figure 1 is a front elevation of one form of deviceembodying my invention. Fig. 2 is an end elevation. Fig. 3 is a planview.' Fig.4 is a sectional view, partly in elevation, showing how theblade is clamped between the guard and the backing members. Fig. 5 is aninverted sectional plan view, showing how the locking member engages apart of the backing member; and Fig. 6 is a detail plan view of one formof blade that may be used.

The handle member 10 may be of the usual or of any preferredconstruction and may have a guard member 11 held thereto as by a rivetor stem portion 12, or in any desired manner. This guard member is substantially rectangular in form and is provided with teeth 13 at one edgeand teeth 14 at the other edge thereof lengthwise of said guard memberso as to form comb-like parts. In said guard member 11 are apertures 15through which are adapted to pass the lugs or posts 16 of the backingmember 17. The backing member 17 is somewhatsmaller than the guardmember 11 and is substantially rectangular in form, and be tween thebacking member and the guard member is held a blade 18. This blade mayhave two cutting edges 19 and may be provided with slots or openings, as20, which are adapted to fit about the pins or posts 16 in such a waythat the said blade may be properly held in position to be clampedbetween the guard member and backing member as will be presentlydescribed.

A locking member or element 21 is pivotally held on the shank of therivet or fastening part 12. The locking member has outwardly projectingarms 22, the ends of which are formed with finger-like parts 23 whichextend in opposite directions, and said finger-like parts or fingers 23are adapted to enter slots 2 1 on the inner surface of the posts 16 at apoint adjacent to the under surface of the guard member 11 when thebacking member is in position. The locking member 21 has a stop or part25 adjacent to each finger 23 to engage the solid part of the posts 16to limit the movement of the locking member, and said finger portions23, as well as the slots 24, may be cam-shaped or so formed that thebacking member 17 wil be forced toward the guard member 18 when thelocking member is moved into engagement with said posts. This lockingmember is'provided with a finger or handle portion 26 on opposite sidesthereof, one on each arm 22, and so an ranged that the said lockingmember may be readily rocked or oscillated with the handle as a pivot toengage the posts and effectively lock the members together.

From the foregoing it will be seen that a simple and efficient safetyrazor is provided in which a locking device or member is adapted to bereadily operated to clamp and hold a flexing or other blade between theguard member and the backing member; that said locking means is simplein construction and is adapted for use in connection with various formsof safety razors; that simple means is provided for guiding the bladesand holding the same in position for use; and that said device is soconstructosts as well as the ed that different degrees of closeness ofshaving may be secured.

Having thus described my invention, I claim as new and desire to secureby Letters Patent .1.'A safety razor comprising a handle, a guard memberon one end thereof, a backing member provided with a projecting posthaving a slot therein, a locking member pivotally held to said handleand having an arm provided with means whereby said locking member may beoperated, a stop on the 1 locking member for limiting the movementthereo and a cam shaped finger portion on said locking memberengaging-the slot of the post whereby the backmg member may be forcedtoward the guard member.

2. A safety razorcomprising a handle, a guard member having openingstherethrough carried by one end of the handle, a' backing memberprovided with posts having slots at the inner sides thereof, said postspassing through the openings in the guard member, a pivotally heldlocking member having oppositely extending arms provided with meanswhereby the locking member may be operated, and with fingers havin camshaped ends and engaging the slots 0 the posts to force the backingmember toward the guard member, and a blade having slots at its endsfitting about said posts and between said guard member and a backingmember.

3. A safety razor comprising a handle, a

backing member on one end thereof, a guard member provided with teeth onthe opposite ed es thereof, the teeth on one edge being difierentlyspaced apart from the teeth on the opposite edge, said backing memberbeing provided with posts having slots at the inner sides thereof, and alocking member pivotally held to said handle and having oppositelyextending arms and provided with cam-shaped fingers engaging the slotsof the posts for locking the backing member to the guard member.

This specification signed and witnessed this 13th day of November A. D.1909.
